无法从 Matlab Coder 创建 .dll

Question

我正在尝试使用 Matlab Coder 工具将一些 matlab 代码转换为 c 动态库 (.dll)。我正在一些简单的示例代码上尝试它，但我不断收到相同的错误，但找不到解决方案。

我的代码是:

function y = lbryTest(x, z) %#codegen
%QUICKTEST Summary of this function goes here
%   Detailed explanation goes here
y = 1.0;
a = x + z;
b = x * a;
y = b/3 + y;
end

我尝试使用应用程序版本的编码器以及命令:codegen -config:dll lbryTest -args {2.0, 5.0}构建日志(包括错误)是:

我可以用这段代码创建一个 .lib，但我需要一个 .dll，这被证明是很困难的。看起来我丢失了一些目标文件或者 matlab 找不到它，但我不知道该怎么办。

感谢 Ryan Livingston 的建议，我正在将其转变为官方答案

文件 lccstub.c(编译为 lccstub.obj)不在您的计算机上，而它应该在您的计算机上。要修复此问题，您应该安装 Matlab 支持的编译器。
